Summary

When you start a Desktop Bridge application (for example, a desktop application that is packaged as a Windows app) on a server that is running Microsoft SQL Server, the application does not start and you receive the following error message:

The data area passed to a system call is too small.

Cause

This issue occurs because of miscommunications between two filter drivers, specifically WCNFS (the Desktop Bridge) and the RsFxXXXX.sys driver (SQL Server FILESTREAM system driver). The RsFx system driver doesn't appropriately honor flags being passed by the WCNFS driver. This causes startup failures of any Desktop Bridge application.
